FASTENING FOR CAR SAFETY-CHAINS.

SPECIFICATION forming part of Letters Patent N o. 720,224, datedFebruary 10, 1903.

Application filed August l1, 1902.

:To all whom t may concern:

Be it known that I, ANDREW CHEISTIANsoN, a resident of Allegheny, in thecounty of Allegheny and State of Pennsylvania, have in- Vented a new anduseful Improvement in Fastenings for Car Safety-Chains; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to railway-cars, and

:lo more especially to means for securing safetychain eyebolts to ametallic car.

The invention consists in the details hereinafter described and claimed.

In the accompanying drawings, Figure 1 is r 5 a plan View, partly insection, of the end lof a car, showing my invention applied thereto.Fig. 2 is a longitudinal section through the end of the car, showing theeyebolt and fastening means in side view. Fig. 3is a section zo on theline 3 3, Fig. 2; and Figt is a side view of the connecting-angle.

The car-body may be of any desired or preferred construction, that shownin the drawings comprising a metallic end sill 1, having z5 a verticalweb and an inturned flange 2 at its bottom.

3 shows a floor plate having upturned lianges at its edge whichfloor-plates are riveted to the end and side plates of the car.

The specific form' of end sill'shown has its web continued upwardly toform the end plate of the car; but this is not essential.

The safety-chain eyebolt is shown at' 4, having the eye at its outer endand having a 3 5 shank 5 extending through a hole in the end sill, andalso havingy a shoulderor collar 6, which bears against said end sill.

7 is a section of angle-bar having its horizontal ange riveted to thedoor-plate 3 and 4o having its forward end abutting against the end sillor end plate of the car. To the vertical fiange of this angle-bar issecured a strap 8, which encircles the shank of the eyebolt and has twoiianges which t over the vertical iange of the angle 7. .Rivets, bolts,or othery suitable devices pass through the iianges of the strap andthrough the vertical flange of the angle 7 and unite these members. Thestrap 8 is attached to the angle 7 in such 5o position that its forwardend is flush with the forward end of the angle, so that the ends of boththe strap and the angle bear securely Serial No. 119,230. (No model.)

against the end sill or end plate. This partially relieves the rivetswhich unite the strap to the angle and also the rivets which unite theangle to the Hoor of shearing stresses. The shank of the eyebolt 4passes through the strap and is provided at its rear end with threadsforreceiving a nut 9, which holds the eyebolt from pullingout. This nut,together 6o with the collar G, bearing against the front face of the endsill or plate, firmly binds the strap 8 to the end sill or plate.v Thevertical fiangeof the angle 7 is cut away at its rear portion, as shownat 10, in order to provide clearance for turning the nut 9.

The angle 7 and strap 8 are simple of construction and provide a secureholding means for the safety-chain eyebolt.V They are so connected tothe car as to relieve the con- 7o necting rivets or bolts of Amost ofthe shearing stress.

It is obvious that in place of the angle-bar 7 any other flanged shapewhich will provide a downwardly-projecting flange may be used. 7 5 AT-bar is one example of such other fianged shape.

Whatllclaim as my-invention, and desire to secure by Letters Patent, is-

l. In a railway-car, the combination with a 8o metallic floor and endsill, of a safety-chain. eyebolt projecting through the end sill, anangle-bar attached to the floor, a strap surrounding the shank of theeyebolt and secured tothe vertical flange of said bar, and a nut or thelike on the end of the shank of the eyebolt bearing against one end ofthe strap.

2. In a railway-car, the combination with a metallic floor and end sill,of a safety-chain 9o eyebolt projecting through the end sill, of a angedbar secured to the ioor and having a downwardly-projecting ange, a strapsurrounding the shank of the eyebolt and having its edges secured tosaid' downwardly- 95 projecting iiange, and means for securing the shankof the eyebolt in said strap.

In testimony whereof I, the said ANDREW CHRISTIANSON, have hereunto setmy hand.

ANDREW CHRISTIANSON.
